Problems solved by technology

There are many irregular places in each production technology link, mainly there are the following problems: (1) long-term asexual reproduction and self-propagation and self-retention of the provenance have caused the degradation of the propagating material (Chuanxiong Lingzi) of Chuanxiong Rhizoma, Lingzi Lack of quality standards, combined with widespread continuous cropping, lead to poor stress and disease resistance and lower yields
(2) The planting methods are extensive and random, such as significant differences

Embodiment 1

[0038] Experimental study on sowing period

[0039] Table 1 Yield results of experimental plots of Rhizoma Chuanxiong at sowing stage (n=3)

[0040]

[0041] Table 2 Detection results of total alkaloids in Chuanxiong sowing experiment (n=3)

[0042]

[0043] Summary: The yield and content of Ligusticum chuanxiong in different sowing periods have certain differences, and the fresh weight and dry weight are higher around August 21. The test results of total alkaloids are also consistent with this. In August, the later the sowing date, the higher the content of total alkaloids. Therefore, after comprehensive consideration, around August 21 was selected as the suitable sowing date.

Embodiment 2

[0045] Planting Density Experimental Study

[0046] Table 3 Experimental results of different planting densities of Rhizoma Chuanxiong

[0047]

[0048] Table 4 The detection results of total ligustratin in the species amount experiment of Rhizoma Chuanxiong (n=3)

[0049]

[0050] Summary: The yield and content of Rhizoma Chuanxiong with different planting densities have certain differences, and the yield of 0.25×0.3m is higher. The detection results of total alkaloids are also consistent with this, so considering the yield and total alkaloid content comprehensively, the suitable planting density of Ligusticum chuanxiong is 0.25~0.35m×0.3m.

Embodiment 3

[0052] Fertilizer Experimental Research

[0053] Table 5 Yield results of Ligusticum chuanxiong in plot experiment with different fertilizers (n=3)

[0054]

[0055] The results showed that: calcium superphosphate, compound organic fertilizer and decomposed cake fertilizer increased production by 9.29%, 13.20% and 24.70% respectively to the control without fertilization. 15.41%, 11.50%. Plot tests of fertilizer varieties revealed that fertilization of Rhizoma Chuanxiong should fully pay attention to the effect of organic fertilizer on increasing production.

Abstract

The invention discloses a high quality and yield hemlock parsley cultivation technology. The technology comprises field selection, soil preparation, seed preparation, seeding, field management, harvesting and pest control. Neutral soil or subacid soil in which no hemlock parsley is planted in a year is selected; the seeding time is between August 5 and August 25 of a natural year, the planting density is 0.25m * 0.25m, and 8-13 thousand hemlock parsley plants are planted in per mu of field; the hemlock parsley is planted in a rotation manner together with the crops such as rape, wheat and the like, which reduces occurrence of diseases and insect pest as well as loss caused by disease and insect pest, reduces the pesticides consumption and environmental pollution of a farmland, lowers the production cost, improves the utilization ratio of the land, can effectively control the yield and quality of the hemlock parsley and ensure stability and uniformity of the quality of the medicinal material.

Description

technical field [0001] The invention relates to a high-quality and high-yield cultivation technology of Rhizoma Chuanxiong, including comprehensive technical measures such as site selection, site preparation, seed selection, sowing, fertilization, fine field management, reasonable planting mode, and scientific pest control measures. Background technique [0002] Chuanxiong is the dried rhizome of the Umbelliferae plant Chuanxiong, which has a long history of planting. Chuanxiong is mainly produced in Dujiangyan, Pixian, Pengzhou, Chongzhou, Shifang, Xindu and other places in Sichuan Province. In addition, it is also cultivated in Shaanxi, Gansu, Hunan, Hubei, Yunnan, Guizhou and other places, but the output is small. At present, the growers in the main producing areas of Chuanxiong are planting in the traditional extensive mode, which lacks scientific and technical guidance, and its scientificity, standardization and rationality need to be improved. There are many irregular...
